This description addresses a process for the preparation of polyolefins from one or more olefinic monomers comprising combining said olefins under olefin polymerization conditions with: i) a transition metal organometallic catalyst compound; ii) a Lewis acid-base complex where the Lewis acid group is an aluminum or boron compound having at least one halogenated aryl ligand and the Lewis base group is an amine or ether compound, said combining being conducted in the presence of a tri-n-alkyl aluminum or gallium compound.
Procédé de préparation de polyoléfines à partir d'un ou plusieurs monomères oléfiniques, qui consiste à combiner lesdites oléfines dans des conditions de polymérisation d'oléfines avec (i) un composé catalyseur organométallique de métal de transition, et (ii) un complexe acide de Lewis/base de Lewis, le groupe acide de Lewis étant un composé d'aluminium ou de bore ayant au moins un ligand aryle halogéné et le groupe base de Lewis étant un composé amine ou éther. Ladite combinaison est effectuée en présence d'un composé de tri-n-alkyle-aluminium ou de tri-n-alkyle-gallium.
